Cellular processes

PP for Notes on Cellular Processes to address Oregon State Science Standard 7-2.4

1. Cellular Processes
Standard 7-2.4

2. Diffusion
One way in which materials move across the cellular
membrane
Materials move from area of higher concentration to
area of lower concentration

4. Osmosis
The diffusion of water across the cellular membrane

5. PHOTOSYNTHESIS
Plants use light energy (for example sunlight)
to combine carbon dioxide and water to make
simple sugars.
Plant cells also release oxygen gas.
Once the sugars are formed, they are either
used by the plant or stored in the vacuoles.
Photosynthesis occurs in the chloroplasts.

7. RESPIRATION
All organisms, including plants and animals,
break down simple sugars into carbon
dioxide and water and release energy.
The cell uses the energy to build, repair, and
reproduce cells.
Respiration occurs in the mitochondria of
cells.

9. WASTE ELIMINATION
Organisms rid the cells of waste products that could
be harmful to the cell.
As waste particles accumulate in a cell, the waste will
move out of the cell and be eliminated.
The waste particles will move from a more
concentrated area to a less concentrated area.

10. MITOSIS
Cell reproduction is called mitosis and occurs in
the nucleus of the cell.
Mitosis enables a cell to make an exact copy of it.
Mitosis is a process of cell division, which results
in the production of two daughter cells from a
single parent cell.
The daughter cells are identical to one another and
to the original parent cell.
Mitosis is needed for growth, replacement, and
Asexual reproduction.
